"He goes beyond his duties as Elle's consultant to make sure she is comfortable and as healthy as she can be when having her treatments and medication.

"He is a huge credit to the NHS."

Dr Jayaram, consultant paediatrician at the Countess of Chester Hospital: "I've watch Elle and her family deal with the burden of cystic fibrosis since she was a diagnosed with the condition at 15 months-old.

"Elle has already had to devote too much of her short life to the daily medications and treatment that keep her alive.

"Every day she must take dozens of tablets, do two hours of physiotherapy and carry an oxygen cylinder around with her wherever she goes.

"Since her health has deteriorated she also has to spend two weeks in hospital every two months and is in desperate need of new lungs.

"Despite all this, Elle remains one of the toughest, bravest and most positive little girls I know and I'm proud to appear in this film with her and help raise awareness of the Cystic Fibrosis Trust's work to beat this disease."

Cystic fibrosis is a life-shortening genetic condition that causes lungs to become clogged with mucus, making it hard to breathe.

There are over 10,500 people with cystic fibrosis living in the UK.

Half of those who die from cystic fibrosis are aged 28 or younger.

Figures from NHS Blood and Transplant show there are currently 6,451 people in the UK in need of an organ - including 153 children.

James Barrow, head of external affairs at the Cystic Fibrosis Trust said: "This time last year Elle was told she may not live for another year, but thanks to the incredible support of her CF team, she has the chance to spend another Christmas with her family.

"Sadly Elle is just one example of how cruel this condition can be - there is almost 11,000 people living with CF in the UK, and millions carrying the gene.

"We need to raise awareness and with support we can beat cystic fibrosis for good."
